thank you. >> senator brown referred to warren as "professor warren" all night. the debate was also marked by a couple of stumbles, one there each candidates. ms. warren ran into trouble on the issue of bipartisanship while senator brown drew jeers from the crowd when asked to name his model supreme court justice. >> can you name some republicans in the senate today that you are able to work with on big issues, substantive issues, that the country faces? >> i think probably richard lugar would be one that would come to mind. >> he's not going to be there. >> he's not going to be there. >> who else would you name, senator? >> that is a problem. let me just -- no, let me do this. >> let me just ask the question. are there any republicans who are actually going to be in the senate that you feel you could work with substantively and compromise with? >> look, it depends on what the subject matter is. >> let me see here. that's a great question. i think justice scalia is a very good judge, justice kennedy, justice kennedy is obviously very good, and justice roberts. ju
